Event Description

It was reported to fresenius by a user facility clinic manager (cm) that a patient experienced an allergic reaction to the optiflux f180nre dialyzer. During followup the cm stated that the patient was approximately 1h10 minutes into treatment on a fresenius hemodialysis (hd) machine (with fresenius bloodlines) when their blood pressure increased and they experienced swelling of the face, throat constriction, and labored breathing. The cm indicated that the patient required medical intervention (specifics unknown). The patient was sent to the emergency room where they were evaluated and released. Since this event, the patient utilizes revaclear 300 dialyzers.

Manufacturer Narrative

A temporal relationship exists between hd therapy utilizing the fresenius optiflux 180nr dialyzer, and the serious adverse events of hypertension, facial swelling, throat constriction and labored breathing, which required an unspecified medical intervention as well as evaluation in the er. The definitive cause of the events is unknown; therefore, causality could not be firmly established. However, the patient¿s clinical manager reported the patient had a favorable response to an alternative dialyzer (baxter revaclear), which offered a substitute mode of sterilization. The cm reported the patient underwent hd without a return or worsening of the symptoms. Limited information precluded a more comprehensive investigation. Based on the totality of the information available, the fresenius optiflux 180nr dialyzer cannot be excluded from having a possible causal and/or contributory role in the patient¿s serious adverse events. While uncommon, hypersensitivity reactions are known to occur with the use of optiflux dialyzers and/or other elements in the extracorporeal circuit. Additionally, hypersensitivity reactions have been known to occur days, months, even years after use with the same dialyzer model. The plant investigation is in process. A supplemental mdr will be submitted upon completion of this activity.  .
